Azure Powershell 中多个应用服务的访问限制 AddIP

我有一个 Azure powershell 脚本，用户必须在其中添加应用服务名称、IP 地址等。我有 4 个网络应用程序，我想向其中添加相同的 IP 地址。我想对应用程序服务名称进行硬编码，以便用户不必输入它。我怎样才能在powershell中实现这一点？这是我的代码：

    Param
(
# Name of the resource group that contains the App Service.
[Parameter(Mandatory=$true)]
$RGName,

# Name of your Web or API App.
[Parameter(Mandatory=$true)]
$WebAppName,

# priority value.
[Parameter(Mandatory=$true)]
$priority,

# WhitelistIp values.
[Parameter(Mandatory=$true)]
$IPList,

# rule to add.
[PSCustomObject]$rule


)
function Add-AzureIpRestrictionRule
{
$ApiVersions = Get-AzureRmResourceProvider -ProviderNamespace Microsoft.Web | 
Select-Object -ExpandProperty ResourceTypes |
Where-Object ResourceTypeName -eq 'sites' |
Select-Object -ExpandProperty ApiVersions

$LatestApiVersion = $ApiVersions[0]

$WebAppConfig = Get-AzureRmResource -ResourceType 'Microsoft.Web/sites/config' -ResourceName $WebAppName -ResourceGroupName $RGName -ApiVersion $LatestApiVersion

$WebAppConfig.Properties.ipSecurityRestrictions = $WebAppConfig.Properties.ipSecurityRestrictions + @($rule) | 
Group-Object name | 
ForEach-Object { $_.Group | Select-Object -Last 1 }

Set-AzureRmResource -ResourceId $WebAppConfig.ResourceId -Properties $WebAppConfig.Properties -ApiVersion $LatestApiVersion -Force 
}
$IPList= @($IPList-split ",")
Write-Host "IPList found "$IPList"."
$increment = 1
foreach ($element in $IPList)
{
if ($element -eq "" -OR $element -eq " ") {continue}
else
{
$element=$element.Trim()
$rule = [PSCustomObject]@{
ipAddress = "$($element)/32"
action = "Allow"
priority = "$priority"
name = "WhitelistIP"+ $increment}
$increment++
Add-AzureIpRestrictionRule -ResourceGroupName "$RGName" -AppServiceName "$WebAppName" -rule $rule
}
}
$OutboundIP = @(Get-AzureRmWebApp -Name "$WebAppName" -ResourceGroupName "$RGName").possibleOutboundIPAddresses -split ","
$increment = 1
foreach ($element in $OutboundIP)
{
$rule = [PSCustomObject]@{
ipAddress = "$($element)/32"
action = "Allow"
priority = "$priority"
name = "OutboundIP"+ $increment}
$increment++
Add-AzureIpRestrictionRule -ResourceGroupName "$RGName" -AppServiceName "$WebAppName" -rule $rule
}

所以我$WebAppName希望它是硬编码的，但是我有 4 个这样的网络应用程序，如何让这个脚本运行 4 次，只需让用户输入他的 IP 地址一次，所有变量保持不变，只是$WebAppName应该更改为我给出的硬编码值
